Abstract
The invention relates to nucleic acids encoding antibody or antibody fragments that specifically binds to an epitope on an intact human IL-6 polypeptide, which epitope when ascertained by epitopic mapping includes one or more residues comprised in each of the following IL-6 fragments (i) a fragment consisting of amino acid residues 37-51 of human Il-6, (ii) a fragment consisting of amino acid residues 70-84 of human Il-6, (iii) a fragment consisting of amino acid residues 169-183 of human Il-6, (iv) a fragment consisting of amino acid residues 31-45 of human Il-6 and (v) a fragment consisting of amino acid residues 58-72 of human IL-6.

138. A nucleic acid or nucleic acids, which nucleic acid or nucleic acids separately or in combination encode for the variable heavy (VH) and the variable light (VL) regions of an antibody or antibody fragment specifically binds human IL-6, wherein said antibody or antibody fragment specifically binds to an epitope on an intact human IL-6 polypeptide, which epitope when ascertained by epitopic mapping using overlapping linear peptide 15-mer fragments which span the full length of the native human IL-6 polypeptide includes one or more residues comprised in each of the following IL-6 fragments (i) a fragment consisting of amino acid residues 37-51 of human Il-6, (ii) a fragment consisting of amino acid residues 70-84 of human Il-6, (iii) a fragment consisting of amino acid residues 169-183 of human Il-6, (iv) a fragment consisting of amino acid residues 31-45 of human Il-6 and (v) a fragment consisting of amino acid residues 58-72 of human IL-6 and which antibody or antibody fragment further competes with an antibody comprising the variable light and heavy regions in SEQ ID NO:
- 2 and 3 for binding to human IL-6.
